Substrate Quality & Pre-Treatment
Concrete
The concrete shall be thoroughly clean, free from dust, loose material, surface contamination and materials which reduce bond or prevent suction or wetting by repair materials. De-laminated, weak, damaged and deteriorated concrete and where necessary sound concrete shall be removed by suitable mechanical or very high pressure waterblasting techniques. Tying wire fragments, nails and other metal debris embedded in the concrete should be removed where possible.
The edges where concrete is removed should be cut at a minimum angle of 90o to avoid undercutting and a maximum angle of 135o to reduce the possibility of debonding with the top surface of the adjacent sound concrete and should be roughened sufficiently to provide a mechanical key between the original material and Sika Repair material.
Ensure sufficient concrete is removed from around the full circumference of the reinforcement to allow application of the reinforcement corrosion protection coating (if required) and compaction of the repair material.
Steel Reinforcement
Rust, scale, mortar, concrete, dust and other loose and deleterious material which reduces bond or contributes to corrosion shall be removed. Surfaces shall be prepared using abrasive blast cleaning or high pressure water-blasting techniques to a minimum standard of SA 2 (ISO 8501-1) If these types of techniques are not permissble contact Sika® Ltd for alternative options using hand preparation techniques and Galvanic Anodes.
Where exposed reinforcement is contaminated with chloride or other material which may cause corrosion, the reinforcement shall be cleaned by low pressure waterblasting before application of reinforcement corrosion protective coating.
Reference shall be made to EN1504-10 for specific requirements - or call our technical team for help: 0113 2455450
Mixing
Sika MonoTop®-630 Rapid can be mixed with a low speed (< 500 rpm) hand drill mixer. In small quantities, Sika MonoTop®-630 Rapid can also be manually mixed. Pour the recommended water in a suitable mixing container. While stirring slowly, add the powder to the water and mix thoroughly at least for 3 minutes adding additional water during the mixing time if necessary to the maximum specified amount and adjust to the required consistency.
Application
Part of the Sika Mortar System; please refer to the data sheet for system strcture and application in different environments.
Curing Treatment
Protect the fresh mortar immediately from premature drying for a minimum of 3 days using an appropriate curing method e.g. curing compound, moist geotextile membrane, polythene sheet etc. Curing compounds shall not be used when they adversely affect subsequently applied products and systems.
Reference shall also be made to BS EN1504-10 for specific requirements - or call our technical team for help: 0113 2455450
Cleaning
Clean all tools and application equipment with water immediately after use. Hardened material can only be mechanically removed.
Limitations
For all queries relating to the use of this product, our technical team should be consulted on 0113 2455450.
- Refer to recommendations provided in BS EN 1504- 10.
- Avoid application in direct sun and/or strong wind and/or rain.
- Do not add water over recommended dosage.
- Large/deep repairs may be subject to shrinkage and cracking. This may be minimised by limiting repair volumes and reducing layer thicknesses.
- Apply only to sound, prepared substrates.
- Do not add additional water during the surface finishing as this will cause discoloration and cracking.
- Protect freshly applied material from freezing.
